Description

We currently return Specified tier type is unsupported when actually the tier might be supported, just the credentials are wrong or some other problem has occurred. This adds another error type with the message Failed to setup remote tier, check credentials so that mc returns this:

❯ ./mc ilm tier update ...wrong creds...
mc: <ERROR> Unable to edit remote tier. Failed to setup remote tier, check credentials.

We could even expand this to be even more specific or return actual error, if anyone thinks it should be done?
